As usual, dr. Fowler is right on with her answer. At the moment, i'm between patients myself witting a quick response.
I actually never heard of this site until a few days ago, and i think it's going to take time before more doctors are aware of this and participate in answering questions. I also think a lot of doctors tend to only look at their area of practice or interest, not every single question that's posted.
I also don't have any means by which to cross-reference your original question, so i can't give you any advice. Perhaps you should re-post your question so it appears again, so doctors who might have missed it but were willing to post an answer can get another crack at it.
